The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
The human senses can be used as analytical tools to evaluate many different aspects of our daily lives. The use of our senses through organoleptic methods offers unique and powerful insights into the characteristics of different stimuli. Due to the unique function of the different sensory organs we use to...
Soil surveys provide essential information for making land use and management decisions on publicly-owned lands in the semi-arid Great Basin. Soil maps produced with conventional mapping techniques are time-consuming, costly, and do not explicitly document the soil scientist's mental soil-landscape model. Predictive soils mapping using decision tree analysis (DTA) can...
Analysis of satellite ocean color, sea surface temperature, and sea ice cover data reveals consistent patterns between biological production, iron availability, and physical forcings in the Southern Ocean. The consistency of these patterns, in conjunction with information on physical conditions during the last glacial maximum (LGM), enables estimates of export...
Many initially healthy Pelargonium seedlings developed symptoms
of Verticillium wilt in an Oregon State University greenhouse
when they attained blooming age. The symptoms first appeared in
May as "edge burning," yellowing, and wilting of leaves. In late
summer, these seedlings which were the offspring of Verticillium
infected plants, became severely...
Twelve chemicals (Busan 72, Chloropicrin, Dacthal, Dexon,
Duter, EP 161, Lanstan, Methyl bromide, Phaltan, Vapam, Vidden D,
Vorlex) were tested to determine their effect on populations of certain
important soil-borne microorganisms including the onion pink root
fungus Pyrenochaeta terrestris. The soil used was from a field in
Malheur County, Oregon...
American hop growers have historically dried hops in the range of 140-155°F/ 60-68°C using deep bed kilns (24 – 32 inches/ 60 – 81 cm), but over the last 10 years they have shifted to lower temperatures (125 -135 °F/ 52 – 57°C) for drying new American aroma cultivars. Reduced...
The interest in the effects of television violence on children has resulted in
thousands of studies over the last 20 years. Previous research on laughter has
generated many laughter theories and several studies show that laughter may
influence mirth expressions and funniness ratings of material. The purpose of
this study...
